+ //===-- llvm-bcanalyzer.cpp - Byte Code Analyzer --------------------------===//
+ // 
+ //                     The LLVM Compiler Infrastructure
+ //
+ // This file was developed by Reid Spencer and is distributed under the 
+ // University of Illinois Open Source License. See LICENSE.TXT for details.
+ // 
+ //===----------------------------------------------------------------------===//
+ //
+ // This tool may be invoked in the following manner:
+ //  llvm-bcanalyzer [options]      - Read LLVM bytecode from stdin
+ //  llvm-bcanalyzer [options] x.bc - Read LLVM bytecode from the x.bc file
+ //
+ //  Options:
+ //      --help      - Output information about command line switches
+ //      --nodetails - Don't print out detailed informaton about individual 
+ //                    blocks and functions
+ //      --dump      - Dump low-level bytecode structure in readable format
+ //
+ // This tool provides analytical information about a bytecode file. It is
+ // intended as an aid to developers of bytecode reading and writing software. It
+ // produces on std::out a summary of the bytecode file that shows various 
+ // statistics about the contents of the file. By default this information is
+ // detailed and contains information about individual bytecode blocks and the
+ // functions in the module. To avoid this more detailed output, use the 
+ // -nodetails option to limit the output to just module level information.
+ // The tool is also able to print a bytecode file in a straight forward text 
+ // format that shows the containment and relationships of the information in 
+ // the bytecode file (-dump option).
